GAS-TURBINE ENGINE.

Specification of Letters Patent.

Patented Oct. 11, 19141.

Application led July 21, 1909. Serial No. 508,737.

To all 'whom it may concern:

Bc it known that l, llVlnLiAM A. Reno, a citizen of the United States, residing in the city of Hollywood, county of Los Angeles, State of California, have invented new and useful Improvements in (lrasTurbine Engines, of which the following is a specification.

Among the Objectis of my invention are the following: to relieve the compression piston from the force of the explosion; to compress the explosivek mixture against a certain amount of pressure in the explosion chamber; to provide impact impulses given in quick succession to'the turbine wheel at di'erent points of its periphery; to regulate the admission of the exploded gases to the turbine wheel, whereby the speed of the engine may be controlled.

Other objects will be hereinafter state and fully described.

I accomplish these objects by the mechanism described herein and illustrated in the accompanying drawings forming a part hereof, in: which' Figure'l is a front elevation. Fig. 2 is a' longitudinal section. Fig. 3 is a front elevation of the port regulating or adjusting ring. Fig. 4 is a diagrammatic top plan section of theexplosion chamber and vanes.

n -a suitably constructed casing 6` is revolubly mounted' the driving shafitl7 from which power 1s taken to operate thpId-rivcn machinery.- At one end of said casing" and Within the same is the vane chamber 8. Secured to the shaft within the vane chamber and arranged to rotate therein is the turbine wheel which is preferably made up in detached sections consisting yof revoluble peripheral vanes 9 having hubs 10.

'The hub of one vane 1s preferably recessed in the vane adjacent thereto as shown at 11, Fig. 2, as thereby a tighter joint is provided. The different sections are secured together by bolts, one of which 12 is shown in Fig. 2 in full lines. The central portion of the outer Walls of the vane chamber is composed of ,detached sections 13 which are provided lwith inwardly projecting' delecting varies 14. These sections are secured in place by bolts, one of which 15 is'shown in full lines in Fig. 2. The impact faces of the .vanes are preferably the arc of a circle. An exhaust pipe 16 opens from the vane chamber and leads the exhaust to any desired oint. At one side of the vane chamber an in the central vfuel supply chamber 21 and connects with port 19. A liquid fuel supply pipe 22 leads from a source of supply not shown and opens into this chamber. The casing of supply chamber 22 is connected by brackets 24 with .the main casing. Valve stopper 18 is noi.

mally held on its seat byspring 25. A screw threaded valve 23 extends through the casing of the supply chamber and normally closes channel 20.

Projecting radially from`the feedingchamber are a plurality of circular chambers, the inner portions 26 of which may be termed compression chambers and the outer portions may be termed the explosion'chambers 27. The compression and 'explosion chambers are separated by a web 28 having a ort 29 therein which is controlled by va ve 30 which has a stem 31. On the top of stem 31 is secured a collar 32. Spring 33 has one end thereof secured to collar 32 and the other end is secured to the casing of ,the explosion chamber and normally holds valve A30 on its seat.

Thewall ofthe explosion chamber near est to the vane chamber is preferably semicircular 'and is a little smaller than the outer wall thereof and forms in combination with the outer wall, two outlet ports 34, which open into the direction changing chamber 35. As shown in Figs. 2 and 4, this direction changing chamber in the top-portion thereof has a horizontal portion which is substantially the same width as the explosion chamber, and then has a vertical portion which .gradually narrows and projects forwardly and terminates in a narrow vertical port 36 through which the exploded gases pass and impinge against the rotating Vanes. An annular recess 37 is provided adjacent to these ports, and in said recess is mounted theannular port controller 38 which has apertures 39 therein. This port controller has an arm 40 which is provided with teeth 4l that are adapted to mesh with worm 42 which is suitably mounted in bearings, one of which 43 is shown in Fig. 2. A crank 44 may be secured to one end of the into the vane chamber; vanes in said vane chambers; and means to operate the pistons. 2. In a gas turbine a plurahty of radially Aarranged compression chambers, each chamber having a piston therein; a driving shaft' means secured to said shaft to operate sai piston; valves in the ends of said pistons; a

feeding chamber in communication with said compression chambers; radially arranged explosion chambers in communication with the outer ends of sald compresslon'.

t shaft, and radially arranged deflecting vanes secured to the vane chamber casing, and pro-l jecting toward the shaft, said delecting Yanes alternatin with the rotatin vanes.

3. In a gas tur ine a plurality o compression chambers, each chamber having a piston therein; a driving shaft means secured to said shaft to o erate said iston; valves in the ends of sai pistons; a eeding cham- /er in communication with said compression chambers; a vane chamber having an exhaustport; explosion chambers in communication at one. end with the compression chambers, and at theother endwith the vane chamber; rotary vanes Within the vane chamber secured'to the driving shaft.

4. In a gas turbine a pluralit of compression chambers istons in sai compression chambers; a riving shaft; means secured to said shaft to operate said pistons; valves in the outer ends of said pistons; a feeding chamber in communication with said compression chambers; a vane chamber having an exhaust port; explosion chambers in communication with the compression chambers and with the vane chambers; means to control the admission of exploded gases from the ex lesion chamber into the vane chamber; an rotary vanes, Within the vane chamber .secured to the driving shaft. In witness that I claim the foregoing I have hereunto subscribed my name this 14th day of July, 1909.
